It isn't something we have been looking at, as our current customers and target applications would have our chip as a standalone embedded processor. We are working on a prototype PCIe card with an FPGA to be able to convert our SerDes to something a PC can talk to, but it isn't really a priority unless we have someone come to us directly asking for it. As for upstreaming, it is something that we want to do, but are not sure if it will be accepted as our chip is not generally available at the moment. It would probably be done around the same time as our next tape out (which would be in larger quantity than our first one) when we would have generally available development kits this coming winter. I have been working on public documentation in my spare time... originally supposed to go out in March but we have had other priorities. If you watch my Stanford talk I show the basic ISA overview as well as the WIP documentation made using doxygen. I'm hoping to get stuff out on our website before our next media push in ~June.
